Background

The SRT Demon is a more powerful wide body version of the Challenger. It debuted during the New York Auto Show in April 2017. The Demon uses an all-new 6.2-liter V8 engine equipped with a 2.7-liter supercharger, which puts out 808 hp (603 kW; 819 PS) with 91 octane gasoline and 840 hp (626 kW; 852 PS) with 100 octane fuel or higher (both outputs are with the red key). Torque stands at 770 lb⋅ft (1,044 N⋅m) on 100 octane fuel. The car weighs 98 kg (215 lb) less than the Hellcat, the total being 1,930 kg (4,254 lb). The car will be using a set of road tires by Nitto Tire, called the NT05R. The tires are the 315/40R18 variations at both front and rear. The tires are targeted for the drag strip, but have enough footprint to make it legal for the road. This tire, although an NT05R consumer tire, is a variation built specifically to withstand the power output of the Demon. This makes the Challenger SRT Demon the first production car to contain a set of drag radial road tires. The SRT Demon contains a system that is used specifically for drag racing called transbrake, which is a mechanism that puts the transmission in 1st gear and the reverse gear simultaneously, holding the Demon stationary. This is used along with the car's torque converter to build up hydraulic pressure before launch. The power-to-weight ratio of the SRT Demon is 418 hp (312 kW; 424 PS) per ton on 91 octane gasoline and 435 hp (324 kW; 441 PS) per ton on 100 octane or higher. It reaches 0–30 mph (0–48 km/h) in 1.0 second, 0–60 mph (0–97 km/h) in 2.3 seconds (2.0s with a rollout), 0–100 mph (0–161 km/h) in 5.1 seconds, a top speed of 168 mph (270 km/h) (factory limited), and the quarter mile (400 m) in only 9.65 seconds at 140.09 mph (225.45 km/h). This makes the Demon the fastest non-electricproduction car to reach 0-60 mph (0–97 km/h) and to complete a straight-line quarter mile at its time of announcement. The SRT Demon is also capable of accelerating at 1.8 G's of force at launch, making this the hardest launching production car ever. The Demon can also push the boost to 14.5 psi and redline up to 6500 rpm. With this extreme power, and hard accelerating, the SRT Demon is the first production car to ever perform a wheelie. With the control module from the "Demon Crate" and high-speed tires, the Demon has reached over 200 mph (320 km/h) in test runs. Because of the lack of an NHRA certified roll cage, which is required if the quarter mile time is under 10 seconds, the NHRA banned the vehicle from competition.

The Dodge Charger was redesigned for 1968, and an initial 35,000 units were slated for production. The demand was so high, however, 96,100 Dodge Chargers were actually produced. Based on the Chrysler B platform, the model years received various cosmetic changes to the exterior and interior including: an undivided grill, rounded tail lights, and hidden headlights. The powertrains were the same as the ones used in the 1967 Charger. The model was not successful in stock car racing such as NASCAR. A more aerodynamic shape formed the Charger 500 model that became the basis for the 1969 Dodge Charger Daytona.
